Sometimes a cracked tooth gives you warning signs. But in other cases, the first clue is when a large chunk of tooth breaks off. Many of these teeth have large silver fillings in them and may appear dark from the amalgam staining that occurs over time. A broken tooth may be sensitive to cold and hot or have sharp edges that annoy the tongue, although they rarely ache. Don’t be fooled: a broken tooth needs attention to prevent further problems from developing down the road.
In other cases, a tooth sends you warning signals that it’s cracked and in danger of getting worse. If your tooth twinges with a cold drink but feels fine to chew on, it’s probably not damaged. If you’ve tried a sensitivity toothpaste for a couple of weeks without any change, you still might want to find out the cause. But if you bite down on certain foods and experience a sharp, sudden pain in the same area, you’d better schedule to see us. Usually, this means the crack is expanding slightly under pressure and will likely worsen over time.
